| Session Description | The Earth’s Critical Zone and associated terrestrial life is governing by two interdependent surface processes, namely erosion and weathering. A combination of atmospheric carbon dioxide levels and continental weathering intensity controls the Earth’s climate on glacial-interglacial timescales. Recent chemical weathering investigations from East Asia, although only a few, reveal a wide range of chemical weathering conditions that were not previously known. Given the importance of diverse climatic and tectonic regimes in Asia, this session explores the recent advances in chemical weathering using geochemical and clay mineralogical studies of river, lake and ocean sediments, including sedimentary rocks. Chemical weathering studies from oceanic islands, in-land lake systems and comparison between large and small river systems in Asia are most welcome. This session further evaluates the unexplored potential geographical regions for future investigations. |
